What is pelletization technique?
Pelletization is a technique to obtain pellets or spherical particles having a dimensions between 0.5 – 1.5 mm. These multiparticulate systems are either compressed into tablets or filled into capsules.
What is pharmacy pelletization?
Pelletization can be defined as an agglomeration (size-enlargment) process that converts fine pow- ders or particles of bulk drugs and excipients into small, free-flowing, more or less spherical units, called pellets (7).
What are pharmaceutical pellets?
In the pharmaceutical industry, pellets can be defined as small, free-flowing, spherical particulates manufactured by the agglomeration of fine powders or granules of drug substances and excipients using appropriate processing equipment.
Is widely used as pelletization aid in pharmaceuticals?
Methods of preparing pellets: Compaction and Drug layering are the most widely used Pelletization techniques in the pharmaceutical industry. Of the compaction techniques used, extrusion and spheronization is the most popular method.
What are the applications of pellets?
Pellets are majorly used to manufacture sustained release dosage systems of medicines. Some of the advantages include daytime and nighttime activity of the drugs, less dosage frequency, and increased patient compliance.
What is pelletization process Slideshare?
INTRODUCTION • Pelletization: • Pelletization can be defined as an agglomeration (size- enlargement process that converts fine powders or particles of bulk drugs and excipients into small, free-flowing, more or less spherical units, called pellets • “Pelletization” involves the manufacture of agglomerates with a narrow …
What techniques is used for formation of pellets?
Pellets can be formulated using various technique but widely used is “Extrusion Spheronization” technique because of its fast working process without complicated design and high efficiency of pellets production with uniform spherical particles.
What is the main advantage of pelletization is?
1) The heat generated in conditioning and pelleting make the feedstuffs more digestible by breaking down the starches. 2) The palatability of the feed is increased. 3) The segregation of ingredients in a mixing, handling or feeding process is prevented.
How are pellets made in pharmaceutical industry?
In pharmaceutical industries, pellets are multiparticulate dosage form which was formed by the agglomeration of fine powdered excipient and drugs together that leads to the formation of small free flowing spherical or semi spherical particles. This technique is called as pelletization process.
What are the benefits of pellets?

What are the different types of pelletization techniques?
The techniques namely extrusion-spheronization, hot melt extrusion, freeze pelletization, cryopelletization have been discussed along with formulation requirements for the process, parameters affecting pelletization.
What is the history of the pelletization process?
Pelletization process first came into existence way back during the 1950s, when the first product was introduced to the market. These pelletized dosage forms have gained popularity considerably from then because of their distinct advantages, such as ease of capsule filling because of better flow properties of the perfectly spherical pellets; enh…
What is a pharmaceutical pellet?
Pharmaceutical Pellets What is pellet? Small free flowing spherical units ranging in size, prepared by agglomeration of fine powders called pellets. • Their size and shape allow their administration as injections and also for oral drug delivery. • Pellets range in size, typically, between 0.5 – 1.5 mm, though other sizes could be prepared.
How do you make a pelletized dosage form?
Pelletized dosage forms can be prepared by a number of techniques, including drug layering on nonpareil sugar or microcrystalline cellulose beads, spray drying, spray congealing, roto granulation, hot-melt extrusion, and spheronization of low melting materials or extrusion-spheronization of a wet mass.
